The vast majority of people who escape federal income taxes still pay other taxes, including federal payroll taxes that fund Social Security and Medicare, and excise taxes on gasoline, aviation, alcohol and cigarettes. Many also pay state or local taxes on sales, income and property.

That helps explain the country's aversion to taxes, said Clint Stretch, a tax policy expert Deloitte Tax. He said many people simply look at the difference between their gross pay and their take-home pay and blame the government for the disparity.

"It's not uncommon for people to think that their Social Security taxes, their 401(k) contributions, their share of employer health premiums, all of that stuff in their mind gets lumped into income taxes," Stretch said.

Obama has pushed tax cuts for low- and middle-income families and tax increases for the wealthy, arguing that wealthier taxpayers fared well in the past decade, so it's time to pay up. The nation's wealthiest taxpayers did get big tax breaks under Bush, with the top marginal tax rate reduced from 39.6 percent to 35 percent, and the second-highest rate reduced from 36 percent to 33 percent.

But income tax rates were lowered at every income level. The changes made it relatively easy for families of four making $50,000 to eliminate their income tax liability.

Here's how they did it, according to Deloitte Tax:

The family was entitled to a standard deduction of $11,400 and four personal exemptions of $3,650 apiece, leaving a taxable income of $24,000. The federal income tax on $24,000 is $2,769.

With two children younger than 17, the family qualified for two $1,000 child tax credits. Its Making Work Pay credit was $800 because the parents were married filing jointly.

The $2,800 in credits exceeds the $2,769 in taxes, so the family makes a $31 profit from the federal income tax. That ought to take the sting out of April 15.
